Simple File Downloader in Python with a Step-by-Step Guide
Learn by Doing and Build Your Own File Downloader and Level Up Your Skills!
In this guide, weβll explore a basic file downloader implemented in Python using the requests
library. Weβll break down each part of the code so you understand how it works.
The downloader accepts two inputs from the user:
- A URL to download the file.
- The output path where the file should be saved.
It fetches the file from the specified URL in chunks to handle large files, saves the file to the specified path, and handles errors that may occur during the process.
Full Code
import requests
import argparse
def download_file(url, save_path):
"""
Downloads a file from the given URL and saves it to the specified path.
:param url: The URL of the file to download.
:param save_path: The path where the file should be saved.
"""
try:
# Send a GET request to the URL with streaming enabled to handle large files
response = requests.get(url, stream=True)
response.raise_for_status() # Raise an HTTPError for bad HTTP responses (4xx and 5xx)β¦
